Conditions: dental caries
Dental caries, unspecified,

Registration Number: CTRI/2022/03/041134

Brief Summary: Dentalcaries is an infectious transmittable bacterial disease, which is characterizedby a multi-factorial pathology.1 In the early childhood the caries(ECC) have effects on both dental and general health of the child.2Oral health impacts on the quality of life of children 3, 4.However, extreme caries have a noticeable impact on the diameter of the arch.5

Inorder to preserve the functional integrity of primary dentition, it isimportant to perform different restorative treatment due to an increase in theprevalence of dental caries today.6 In all restorative procedures,there is a loss of some amount of tooth structure, these damaged teeth can berestored with various restorative materials such as resin modified glassionomer cement, resin filled composite or resin filled composite.7 Forprimary molar teeth, preformed metal crown were first described by Engle8in year 1950 and followed by Humphrey.9 Since then, crown designmodifications are done, to improve morphology of crown and to simplify thefitting procedure.10 Stainless steel crowns are the first choice forrestoring defects due to caries in primary dentition and the most reliable andsuccessful form of tooth restoration is in pediatric dentistry.9Stainless steel crown placement is easy and economical with a high success ratefor preserving remaining teeth damaged by excessive preparation.11,12Esthetic concern is reported to be the most important problem for dentalrestoration in a study in pediatric patients.13Accordingly, newmaterials have been created to replace SSCs, such as bonded strip crowns,open-faced crowns and pre-veneered SSCs.14,15 These new materialshave enhanced aesthetics but have side effects such as poor gingival health anddental margin exposure due to metal presence.11 In particularpre-veneered SSC veneer resin sometimes chips and results in additional care..15,16

Today,for the restoration of the primary teeth, the dental practitioner has variousoptions like preformed zirconia crowns for esthetic concern. Based ontechnical, functional and esthetic limitations, each technique is associatedwith the own sets of advantages and disadvantages.17, 18, 19

Alternative to these, prefabricated estheticflexible crowns are comparatively new. Flexible crowns allow practitioner toprovide aesthetics of new age crowns and easy, economical as well asconservative preparation of stainless steel crowns in addition to that they can be corrected like SSCs and thatâ€™sthe reason this study is planned
